The U-shaped glass tube in the figure below contains two liquids in mechanical equilibrium: sea water of density 1.025 kg/L, and an unknown liquid of density ρ. The unknown liquid is in the left tube, floating on top of the water with a clearly visible interface. Use h1 = 14.6 cm and h2 = 1.0 cm with the heights as labeled in the figure below. What is the density of the unknown liquid?
